A high level of secrecy shrouds the first teaser that has come from HBO about the forthcoming Game of Thrones season. With no actual footage from the show, this teaser shows off the characters' heads in the "Hall of Faces." Of course, Jon Snow remains up front and center, but his return has not been confirmed or discounted. While this teaser doesn't reveal too much, all our favorite characters are definitely at risk again.

Tune in to the season 6 premiere on April 24 and check out more teasers here and here.
